The power consumption of the ball mill was monitored for two months and the data is shown in the histogram in Figure 2c. It can be seen that the power consumption for each shift varied between 250 and 350 kWh. The data-set is negatively skewed and the average power consumption for each shift during this period was 294 kWh.
In total 76 data sets were generated covering the power draws of ball SAG and AG mills in the range 7 - 7900 kW.

Below 30 microns the advantages of a horizontal stirred mill become dramatic and below a certain point the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption. Stirred mills can produce product down to 7 microns.
Nov 26 2019 From the volume the ball mill divide into industrial ball mill and laboratory use the small ball mill sample grinding test. In addition these mills also play an important role in cold welding alloy production and thermal power plant power production.
Aug 01 2001 Typical power consumption for a 5-m diameter by 7-m-long ball mill is between 2.5 and 3.5 MW. The actual proportion of this energy usefully used in size reduction is thought to be very low perhaps in the range of 1–5. Significant financial and environmental benefits can be obtained by improving this efficiency even slightly.
power draw is significantly affected by the mass of the media in the mill and the machines are designed with flexibility such that media can be added as required to achieve the desire mill power consumption. OVERVIEW OF POWER MODELS Predicting the performance of any of these mills starts with modelling power consumption and energy use.
